Abstract

The invention provides a universal riding wheel rotating speed measuring method and device and a storage medium, and the method comprises the following steps: obtaining x-axis data and y-axis data of a sensor, and carrying out the filtering processing of the two-axis data; performing sparse processing on the double-axis data, and extracting a peak value, a zero point and a valley value of a data waveform; the data features of the x axis and the y axis are combined, whether preset conditions are met or not is judged, when any one of the three preset conditions is met, feature points at the moment and types of the feature points are cached, the type of a peak value is recorded as 1, the zero point is recorded as 0, and the valley value is recorded as-1; and calculating the linear speed of the wheel rotating speed by using three different formulas according to the three conditions. The invention designs a universal rotation speed resolving algorithm which can be suitable for sensing equipment such as an accelerometer, a magnetometer, a stress sensor and the like, plug and play can be realized when the rotation speed of the rotation is resolved, and the detection efficiency and precision are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of speed measurement of wheel rotation speed of cycling vehicles, and in particular relates to a universal cycling wheel rotation speed measurement method, equipment and storage medium. Background technique [0002] Common rotational speedometers generally have a wide variety of sensors, among which gyroscopes, accelerometers, magnetometers and stress sensors are very common. Except for angle measuring devices such as gyroscopes, most sensors need to collect or extract periodic data of rotation for speed calculation. Among them, the solution method based on the angle measuring sensor is relatively simple (integration method), but its power consumption and cost are high; while the low-cost accelerometers, magnetometers, etc. are susceptible to vibration and strong magnetic interference, which brings about feature recognition noise . The invention aims to build a general wheel speed speed measurement algorit...
